7 Claims.

This invention relates to cutting devices.

One of the objects of the invention is to provide a device for cuttinglengths of fragile tubular material into relatively small pieces in acontinuous manner.

Another object of the invention is to provide a device adapted to cuttubular soap such as is described and claimed in my copendingapplication entitled Soap product and method of making same, Serial No.703,350, led December 21, 1933.

Other objects of the invention will be apparent from the description andclaims which follow.

In the drawings similar reference characters in the several figuresrepresent identical parts.

Figure 1 is a side view of the device.

Figure 2 is a plan view of the device shown in Figure 1.

Figure 3 is a sectional view taken on line 3 3 of Figure 2. p

Figure 4 is a view partly in section on line 4-4 of Figure 2 showing thecutting element and adjacent parts in detail.

Figure 5 is a sectional view of the cutting element. v

Figure 6 is aplan view of a portion of the cutter showing the manner ofmounting.

Referring now more particularly to Figure 1:

Tubes of more or less wet plastic soap travelling on belt I of conveyor2 pass over plate 3 to anvil roller 4 and are chopped into pieces as 5by the blade 6 of cutter 1. Screen belt I is supported by cross pieces 8extending between chains I0 driven by sprockets 9. Sprocket gears 9 aremounted upon and driven by shaft I| which is journalled in bushings I2and I3 mounted upon conveyor frame I4. Gear I5 is also mounted uponshaft II and drives gear I6 through` chain I1. Gear I6 is mounted uponshaft I8 as is anvil roller 4. Shaft I8 is journalled in bushings I9 andmounted upon angle iron frame 2|.

Leveler 22 is bolted at each end to brackets 23. Each bracket 23comprises links 24 and 25 mounted on frame 2|. The distance of leveler22 from anvil roller 4 may be adjusted by means of bolts 26 and 21 andslots 28 and 29.

It is the purpose of leveler 22 to prevent tubes of soap as 30 frombeing thrown clear of anvil roller 4 due to the reciprocating action ofcutter 1.

Motor 3| is attached to bracket 32 which is mounted cn frame 2| and maybe adjusted upwardly and downwardly by screw 33. Belt 34 drives wheel 35which ismounted on one end of shaft 36 journalled in arbors 31 and 38.Shaft 3S carries sprocket gear 39 at its opposite end. Shaft 40 isjournalled in arbors 4I and 42 and carries sprocket gear 43. Shaft 44journalled in arbors mounted on frame 2| carries sprocket gear 45. Chain46 drives sprocket gears 43 and 45 receiving power from sprocket gear39.

The construction of cutter 1 is clearly shown in Figures 5 and 6, knifeblade B being clamped to knife frame 41 by blades 48, securely held bybolts 49 and bolts 50. The mounting of the cutter l 1 may be clearlyobserved in Figures 2 and 4. The frame 41, which extends the full widthof the machine, is secured to arms 5I integral with eccentric sheave 52mounted upon shaft 44. Arms 53, which for convenience in adjustment mayinclude turn buckles 54, are secured to eccentric 55 mounted upon shaft4D and pivoted at 56 on frame 41.

This mounting of the cutter gives the cutting edge of the knife blade amotion along a curve such that at the time its cutting edge is incontact with roller 4 it will have a velocity substantially equal .tothat of the surface of the roller and throughout the entire cuttingrange it will be moving in the same direcion and with a velocityapproximately equal to the motion of the material to be cut. With thisarrangement there is nothing which tends to interfere .with the smooth,continuous, and uniform motion of the uncut material through the cuttingdevice.

In practice the eccentricity secured by eccentric sheave 55 and verticalconnecting rods 53 is about 1A", giving a total vertical component tothe knife of about 1/2, the total horizontal motion of the knife bladebeing about based upon an eccentricity of about 1%". The timingrelationship between the horizontal and vertical components is such thatas the knife is descending and cutting the tubes, it will be moving inthe direction of normal motion of the ,tubes and when the knife isascending and is out of the range of the motion of the tubes, it will bemoving in a direction opposite to the normal motion of the tubes.

It has been found in practice that it is desirable to keep thedisplacement of the knife between its extreme positions as small aspossible, in order to reduce the inertia forces acting upon thevariousparts and also to keep to a minimum the velocity of impact of theknife with the material to be cut. i

The size of the pieces into Which the material i is cut is dependent, ofcourse, upon the relationship of the speed with which the material isfed to the anvil roller 4 by the conveyor I and the speed of theoperation of the knife.

The extreme positions of the knife are shown in Figure 4 in dottedlines.

I claim: 1

1. In combination. lmeans for continuously feeding material to a cutter,a guiding leveler for said material, a rotating anvil in operativerelationship with said cutter and means for reciprocating said cuttervertically and laterally.

2. In combination. a rotatable cylindrical anvil, a reciprocating cutterin operative relationship therewith and a leveler positioned before saidcutter to guide material being fed thereto.

3. In combination, a rotatable cylindrical anvil and a reciprocatingcutter in operative relationship therewith, said reciprocating cutterbeing driven by arms mounted on eccentric sheavesV on drive shaftswhereby said cutter is caused to follow in the direction of travel ofsaid anvil while cutting material passing thereover and is returned tocutting position out of contact with said anvil and with materialthereon, the return of the said cutter being in a direction opposite tothe direction of travel of said anvil, and an adjustable levelerpositioned before said cutter guide material being fed thereto.

4. In combination, a rotatable cylindrical anvil and a reciprocatingcutter in operative relationship therewith, said reciprocating cutterbeing driven by arms mounted on eccentric sheaves on drive shaftswhereby said cutter is caused to follow in the direction of travel ofvsaid anvil 4while cutting material passing thereover and is returned tocutti position out of contact with 5.

to said cutter over said anvil and a plate bridging the gap between saidconveying means and said anvil.

7. In combination, a rotatable cylindrical anvil and a reciprocatingcutter in operative relationship therewith, said reciprocating cutterbeingiiriven by arms mounted on eccentric sheaves on drive shaftswherebyA said cutter is caused to 25A follow in the direction of travelof said anvil twhile cutting material passing thereover and is returnedto cutting position out of contact with said anvil and with materialthereon. the return of the said cutter being in a direction opposite tothe direction of travel of said anvil, an endless conveying meanscarrying material to be fed to said cutter over said anvil, a platebridging the gap between said conveying means and 'said anvil, and aleveler positioned over said anvil between said plate and said cutter.to guide material being fed to said cutter.
